Answer:
1. helicase enzyme
2. Eukaryotic DNA is much larger and replication at multiple origins helps reduce the time required for whole genomes to replicate.
Explanation:
1. During DNA replication helicase enzyme is the enzyme that unwinds 2 DNA strands. Hydrogen bonds present between two strands of the DNA helical which are broken by the helicase enzyme and separate both the strands. Unwinding is essential here as it initiates the replication process.
2. There are multiple origin sites in the eukaryotic DNA due to the larger amount of material to be replicated. To reduces the replication time of the entire genome requires multiple origins of replication.
